Abstract
Provided herein may be a storage device and a method of operating the same. The storage device may include a memory device including a plurality of memory cells and a memory controller. The memory controller may be configured to control the memory device to generate dummy data based on write data, when a size of the write data is less than a preset size, and to store program data including the write data and the dummy data in selected memory cells among the plurality of memory cells.
Claims16
A memory device of a storage device, comprising:
- a plurality of memory cells;
- a peripheral circuit configured to perform a program operation on memory cells selected from among the plurality of memory cells;
- and a control logic configured to receive write data from a memory controller of the storage device that is external to the memory device, to generate dummy data corresponding to the write data when a size of the write data to be programmed to the selected memory cells is less than a preset size, and to control the peripheral circuit to store program data including the write data and the dummy data in the selected memory cells, wherein the control logic comprises:
- a dummy data generator configured to generate the dummy data based on the write data;
- and a program operation controller configured to control the dummy data generator to generate the dummy data when the size of the write data is less than the preset size, and wherein the dummy data generator generates the dummy data based on all or part of the write data.
2 more elements
A memory controller for controlling a memory device, comprising:
- a write buffer configured to store write data to be programmed to the memory device;
- and a write controller configured to provide the memory device with the write data and a program command set that includes a dummy generation command indicating generation of the dummy data based on the write data when a size of the write data is less than a preset size, and to store program data including the write data and the dummy data, wherein the memory device generates the dummy data based on all or part of the write data in response to the dummy generation command.
A storage device, comprising:
- a memory device including a plurality of memory cells;
- and a memory controller, which is external to the memory device, configured to provide the memory device with write data, control the memory device to generate dummy data based on the write data, when a size of the write data is less than a preset size, and to store program data including the write data and the dummy data in selected memory cells among the plurality of memory cells, wherein:
- the memory controller provides the memory device with a write address indicating an area in which the write data is to be stored and a program command set including a dummy generation command indicating generation of the dummy data, and the memory device generates the dummy data based on the write data in response to the dummy generation command.
